Does a hognose snake have poisonous breath?

What you might have heard: A Hognose Snake, sometimes called a puff adder, can mix poison with its breath and kill a person at a distance of 10 or even 20 feet.

The real story:Hognose snakes do not produce poison, nor do they blow their breath at other animals or people. They may hiss when threatened, but the only danger from that would be from fright.
